ABSTRACT:
Apparatus for flaring combustible waste gases from oil refineries and the like including a vertical flare stack, a continuously burning pilot burner mounted adjacent the flare stack and a temporary flame retention burner mounted in close proximity to the pilot burner. The pilot burner is provided with a venturi for producing a combustible air-gas mixture and a spark producing device which ignites the combustible mixture in the burner thereby producing a flame front which travels to the top of the burner and ignites the temporary flame retention burner. After the spent gas has been purged from the pilot burner by continuing to flow combustible gas therethrough, the pilot burner is reignited by the flame retention burner, the latter then being extinguished by shutting off its supply.
